Plate Polarizing Beamsplitters

PBS-C

Plate polarizing beamsplitters are a plate that is coated with a polarizing coating.

Catalogue
Optics & Optical Coatings
  • Plate polarizing beamsplitters transmit p-polarization and reflect s-polarization as the monochromatic beam entering is at Brewster’s angle.
  • The losses of input beam of these products are minimized because of no absorption of dielectric coating.
  • Coating characteristic are not influenced marginally by temperature change.
